How secure is the SmartTools MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how SmartTools holds up.
Official endpoint
Operated by SmartTools (smart-tools.xyz) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If SmartTools adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps
Connect your gate
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Pick SmartTools
Choose SmartTools in the gate directory. No sign-in needed.

The SmartTools MCP server at a glance
https://smart-tools.xyz/mcpQuestions, answered
Is there an official SmartTools MCP server?
Yes — SmartTools operates its own remote MCP server at smart-tools.xyz. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.

Add gate's gateway URL to your AI client once, then pick SmartTools in the directory. No account or sign-in is needed. From then on, SmartTools's tools are available in every client you've connected to gate.
